LD56100DPU33R

LD56100DPU33R is a high accuracy voltage regulator provides 1 A of current from an input voltage ranging from 1.8V to 5.5V, with a typical dropout voltage of 120mV. It is available in DFN8 (1.2 x 1.6mm) package, allowing the maximum space saving. The device is stabilized with a ceramic capacitor on the output. The ultra-low drop voltage, low quiescent current and fast transient response, together with the internal soft-start circuit, make the LD56100 suitable for low power battery operated applications. An enable logic control function puts the LD56100 in shutdown mode allowing a total current consumption lower than 0.1 µA. Short-circuit protection with current limit foldback and thermal protection are also included.

• Very low quiescent current (100µA typ at no-load, 0.03µA typ in off mode)
• Output voltage tolerance: ± 1% from -40°C to +85°C
• Ultra-low noise of 13µV RMS noise from 10Hz to 100kHz at VOUT = 3.0V
• High PSRR (70dB at 1kHz)
• Logic-controlled electronic shutdown
• Optional output voltage discharge feature
• Operating temperature range from -40°C to 125°C
